I recently purchased a 110 watt solar panel for my 2011 Wolf Pack 23 DFW. Before I start drilling on the roof and penetrating the shell, I wanted to check here and see if anyone else has experience at mounting things on the roof.

For instance, how thick is the roof, what material is under the shell, what can I expect? I there a possible wire duct to run the wire down to the frame? Is there a best or better place to mount the panel on the roof? Were did you wire the panel/controller into the system?
